Intel 560 Throttled?

I am not sure if this is the correct forum, but I need some advice about my CPU.

Its a Intel PIV 560 (3.6Ghz), its about 13 months old now and has constantly run at a high temp since I first got it. I used to have the Asus Star Ice cooler but it was too noisy (and so heavy it warped the mobo) so I removed this and replaced it with the Retail cooler (and Artic silver 5). Under stress my temp now reaches 75c which I know is not good, however I have a more worrying problem.

My CPU never goes above 70% - at the moment I am running the torture test on Prime95 (Blend) and my cpu is averaging between 60 and 70%, the CPU temp is peaking around 75c.

it looks like my cpu is throttling itself because of the high temps, is that correct?

I have ordered the freezer 7 pro so hopefully that will help with the temps.

Any response welcomed - except those buy an AMD posts hahaha I will be buying an AMD as soon as they support DDR2 lol spent £140 on my RAM want to make the most of it dammit :)

**Edit for spelling DOH!**
 
Thank you for all the comments I will do some testing tonight and see what I can do, the case is a Lian Li V2000 so the air flow should be pretty good, but I did notice it was pretty warm around the northbridge and GPU cooler.

Thanx again for all the feedback.
 
Ahhhh thank you, that makes perfect sense.

I tried all the suggestions above (Thanx guys) and could still not get it passed 60%.

I then tried running two instances of Prime95 as you suggest but Prime95 would not load twice, I could see a new instance open but it would close immediately if I had another copy already running, but I ran CPUBurnIn while I was running Prime and this pushed it to 100% so you were right. Thank you at least I know the CPU is actually doing what its mean to then lol.

I was going to say that whenever I do video encoding I could see that it went to around 90% and I know Hyperthreading is great for video encoding so I guess it makes sense that it would go over the 60% all other tasks are averaging at.

Thank you again for your suggestions - I can put my mind to rest and work on bringing those temps down.
 
I definately have both CPU graphs in Task Manager, I have taken some screen shots, as you can see both CPU's in task manager are definately being utilised but they dont seem to go past 60%.

The spike you see above is when I was opening Photoshop to paste the screens.
 
Hi Agr3sive,

Yeah its an Abit NI8 SLI mobo, I guess it must be something to do with the uGuru sensor, I have tried various sensor monitoring tools and have yet to find one that reads the uGuru sensors correctly. I am stuck with the uGuru application at the moment.
 
UPDATE:

I installed the freezer pro 7 last night - initially everything looked good, temps were low (well low for a 560 lol). However even with low temps it would just hang under a stress test.

I fiddled with a few things and then decided to check the chipset since I already knew that it ran pretty hot. I have a Abit NI8 SLI mobo which has a heatsink with a heatpipe that runs to a set of fins in the backplane of the mobo (Where Audio inputs usually are). When I removed the heatsink the thermal pad just fell off.

It looked pretty cooked and the chip had some residue on which appeared to be some melted thermal paste. Anyhow I cleaned this up and applied some AS5 and reset the heatsink.

Turned the PC on and managed to get a good 15 minutes of stress testing out of it (it was now 3am in the morning so I really wanted to get to sleep haha).

CPU temp after 15 minutes of stress testing was 62 degrees, case temp was 36 degrees.

When idle the CPU temp is 46 degrees and case temp 32 degrees.

With the boxed cooler I could only do about 2 minutes of stress testing before the mobo would start beeping since the CPU temp rose above 75 degrees, so the cooler has reduced the temps by about 15 degrees.

I think I will be investing in a chipset cooler to help reduce the heat a little more.

The CPU cooler is also much quieter than the boxed cooler.

Definately worth the £15 it cost, wish I had done it months ago.

Thanx for all your suggestions :)
